Propylene oxide capped liquid polymeric surfactants for agricultural compositions and agricultural compositions including pesticide

Abstract

Propylene capped liquid polymeric surfactants for agricultural compositions and agricultural compositions including pesticide are provided. For instance, agricultural compositions can include: (a) an agricultural oil; and (b) an agricultural oil-compatible, propylene oxide (PO)-capped liquid polymeric surfactant having the following structure: (I) wherein m is an integer from about 3 to about 7, n is an integer from about 5 to about 20, and o is an integer from about 3 to about 30, and R is a linear or branched C4-C18 alkyl chain.

1 . An agricultural composition comprising:
 (a) an agricultural oil; and   (b) an agricultural oil-compatible, propylene oxide (PO)-capped liquid polymeric surfactant having the following structure:   
       
         
           
           
               
               
           
         
         wherein m is an integer from about 3 to about 7, n is an integer from about 5 to about 20, and o is an integer from about 3 to about 30, and R is a linear or branched C4-C18 alkyl chain. 
       
     
     
         2 . The agricultural composition of  claim 1 , wherein:
 (a) is at least 60 percent, at least 70 percent or at least 80 percent by weight per volume of the agricultural composition; and   (b) is from about 0.5 to 40.0 percent, from about 1.0 to about 20.0 percent, from about 10.0 to about 20.0 percent, or from about 15.0 to about 20.0 percent by weight per volume of the agricultural composition.   
     
     
         3 . The agricultural composition of  claim 1 , further comprising water, and wherein the agricultural composition exhibits lower foaming and improved emulsion stability as compared to agricultural compositions without (b). 
     
     
         4 . The agricultural composition of  claim 1 , further comprising a pesticide. 
     
     
         5 . The agricultural composition of  claim 1 , wherein m is an integer from about 3 to about 6 or an integer from about 3 to about 5. 
     
     
         6 . The agricultural composition of  claim 1 , wherein m is about 5. 
     
     
         7 . The agricultural composition of  claim 1 , wherein n is an integer from about 6 to about 15 or an integer from about 9 to about 14. 
     
     
         8 . The agricultural composition of  claim 1 , wherein o is an integer from about 10 to about 25. 
     
     
         9 . The agricultural composition of  claim 1 , wherein R is a branched C4-C18 alkyl chain. 
     
     
         10 . An agricultural composition including pesticide comprising:
 (a) an agricultural oil;   (b) an agricultural oil-compatible, propylene oxide (PO)-capped liquid polymeric surfactant having the following structure:   
       
         
           
           
               
               
           
         
         wherein m is an integer from about 3 to about 10, n is an integer from about 5 to about 20, and o is an integer from about 3 to about 30, and R is a branched C4-C18 alkyl chain; and 
         (c) a pesticide.
